Description
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention is directed to a large-scale 3D electronic
display system, and more particularly to a large-scale polarizing
3D electronic display system and the manufacturing process.
Description of the Related Art
Generally, the existing techniques in the field of 3D electronic
displays use a pair of shutter mode glasses, and do not include
rapid image-switching between the left eye and the right eye. This
causes serious visual flickering and consequently results in visual
fatigue, and leads to low compatibility between the 3D displays and
the 2D displays.
In all the current large-scale polarizing stereoscopic display
screens, physical pixels are arranged in alternate rows, in
alternate columns, or in odd/even parity arrays. Nevertheless, each
physical pixel includes only one real electronic pixel and,
therefore, is merely capable of emitting light for the left eye
image or the right eye image. As such, all the current large-scale
polarizing stereoscopic display screens have low resolution.
Accordingly, a stereoscopic display screen that has high resolution
and is suitable for both indoor and outdoor application is
desired.

DETAILED DESCRIPTION OF THE EMBODIMENTS
The invention is further illustrated by detailed description of the
embodiments combined with the drawings.
As shown in FIG. 1, the present invention includes 3D electronic
display system 2 that includes a SC electronic controller and a
display screen SN. The SC electronic controller may be a scrambler,
mixer or complex; the display screen SN has a plurality of display
pixels. The SC electronic controller connects with the display
screen SN. The SC electronic controller controls transmission and
image processing. Send the image information data for the left
& right eye to the display screen SN with the SC electronic
controller. Then, separate the left eye image and the right eye
image with a polarization system having a plurality of polarizing
films (the display pixels of the display screen are covered with
the L-type and R-type polarizing films or the polarization boards
which have orthogonal relations between the polarizing angles or
between the polarizing phase, wherein the L-type polarizing film or
polarization board transmits light emitted by the pixel for
emitting light for the left eye, and the R-type polarizing film or
polarization board transmits light emitted by the pixel for
emitting light for the right eye). The SC electronic controller
sends the image information data for the left & right eyes to
the pixels shielded with L-type and R-type polarizing film or
polarizing plate, respectively, to form the left and the right eye
images. When viewing, an observer can wear a pair of polarizing
glasses including polarizing film or polarizing plate having
orthogonal relations between the polarizing angles or between the
polarizing phase to separate the left and the right eye images,
such that the left eye image and the right eye image enter the left
eye and the right eye, respectively, to form a stereoscopic image
in the observer's brain.
The display pixel of the present invention refers to physical
pixel, each display pixel includes two individual electronic
pixels, i.e. inserting two individual electronic pixels within each
display pixel. In this way, stereoscopic display is realized, when
each physical pixel can be divided into two completely individual
pixels, resolution of the left eye and the right eye image have no
loss. The individual electronic pixel in the present invention
refers to a 3-in-1 electronic pixel, that is there are three
primary colors in one electronic pixel and each electronic pixel is
capable of forming full color. Each of two individual electronic
pixels include one left-eye pixel labeled by L for emitting light
for the left eye image and one right-eye pixel labeled by R for
emitting light for the right eye image. The left-eye and the
right-eye pixels can be arranged horizontally, vertically, or
diagonally. Specifically, the left-eye and the right-eye pixels can
be arranged in a row, as shown in FIG. 2; or arranged in a column,
as shown in FIG. 3; or arranged in a right-inclined line, as shown
in FIG. 4; or arranged in a left inclined line, as shown in FIG. 5.
The physical pixel 1 is pointed out in FIGS. 2-5. As shown in FIG.
6, FIG. 7, FIG. 8 and FIG. 9, the display pixels or the display
elements of the display screen can be divided into two sets: the
left-eye pixels L and the right-eye pixels R, and the left-eye
pixels L and the right-eye pixels R can be arranged row by row,
column by column, in a parity array or even parity array. It should
be mentioned that, in every physical pixel, merely two individual
electronic pixels are enclosed wherein, the objective of the
invention would not be achieved if more or less individual
electronic pixels are enclosed in one physical pixel. Moreover, in
every individual electronic pixel, merely three primary colors are
enclosed wherein, that is merely two sets of RGB colors are
enclosed in each physical pixel, the objective of the invention
would not be achieved if more or less sets of RGB colors pixels are
enclosed in one physical pixel.
The light polarizing film may use linear polarization or circular
polarization to polarize light. In linear polarization mode, the
polarizing angle difference between the left eye and the right eye
is 90.degree.; errors are less than .+-.10%. In circular
polarization mode, either the two polarizing angles are in parallel
and the two phases are orthogonal, or the polarizing angles are
orthogonal, and the phases are in parallel, errors are less than
.+-.10%. For the physical pixels, the polarizing films may be
separated, i.e. each polarizing film is set on a single physical
pixel; the polarizing films may be set row by row or column by
column, i.e., the polarizing films are shaped into strips or belts
to set on a row or a column of the physical elements or physical
pixels; or the polarizing films may be set into blocks or plates
for covering or shielding some pixels. The direction of polarizing
light of the display screen SN is consistent with the direction of
polarizing light of the polarizing glasses PG.
when the present invention is applied in a practical SD
(standard-definition), HD (high-definition), or UHD
(ultra-high-definition) display system, since there are two
individual electronic pixels including three primary colors (i.e.,
red, green and blue colors) in each physical pixel for respectively
emitting light for the left and right eyes, there is no pixel loss
to result in the resolution loss. For example, when applying the
display screen comprising a plurality of physical pixels each
having two individual pixels arranged in a column in a practical
SD, HD, or UHD display system, the way of data transmission to the
left and right eyes is demonstrated as in FIG. 10. Such a way of
data transmission ensures that there is no pixel loss to result in
the resolution loss.
The manufacturing process of the invention includes:
step 1, several display pixels are set on the display screen SN;
the display screen SN is connected to the SC electronic controller;
and the display pixels are controlled by the SC electronic
controller to emit light;
step 2, two individual pixels are set at each display pixel, in
which one of the two individual pixels emits light for the left eye
image, and the other emits light for the right eye image; each of
the two individual pixels comprises three primary RGB colors.
step 3, the polarizing film is set on each display pixel. The
polarizing film can be sticked or covered on each display pixel,
fixed on each display pixel by other way. The screen surface can be
waterproof processed for outdoor application.
While particular embodiments of the invention have been shown and
described, it will be obvious to those skilled in the art that
changes and modifications may be made without departing from the
invention in its broader aspects, and therefore, the aim in the
appended claims is to cover all such changes and modifications as
fall within the true spirit and scope of the invention.
